Nike Vaporfly 4 vs Adidas Adizero Adios Pro 4:
Which to Choose

Start with how they drive you forward, because that's the clearest split. The Vaporfly 4 uses a full-length carbon Flyplate suspended in ZoomX foam, which produces a smooth, uniform, forward-tipping roll. The Adios Pro 4 instead uses carbon-infused EnergyRods over dual-layer Lightstrike Pro, giving a more segmented, forefoot-focused snap that rewards toeing off hard. Both feel soft yet lively and both get tippy at easy jog pace, a shared quirk of their tall, slim platforms. The bigger physical difference is cushioning depth: the Adios Pro 4 stacks 39 mm in the heel and 33 mm in the forefoot, versus roughly 36 mm and 30 mm on the Vaporfly 4 — so the Adidas sits taller and holds more foam under the foot, which is exactly why its sweet spot is the full marathon, where that extra protection saves your legs in the closing miles. The Vaporfly 4's lower, more connected profile makes it the nimbler shoe across a wider range, with its sweet spot in the 10K-to-half window and genuine capability down to a sharp 5K. Weight is effectively a wash — both are feathery, in the ~190–200 g range for a men's sample — so neither wins there. Drop is also comparable; both are moderate, forefoot-oriented geometries rather than the high-heel rides of older racers. One practical edge for the Adidas: a Continental rubber outsole gives it dependable grip, whereas the Vaporfly leans harder into shaving weight and trades some outsole and upper durability for it. Both are race-day tools first, with high-mileage longevity a secondary concern.
